- Compatibility Rules
Industrial relay sockets follow international standard dimensions and are interchangeable across brands if:
Pin count matches relay pole number
التصنيف الحالي (≥10A) meets load
تصاعد (DIN-rail/screw) matches panel design
- Terminal Type Selection
Conventional screw: PTF08A / PTF11A / PTF14A-suitable for low-vibration environments
حماية الاصبع: PTFZ series-suitable for areas with frequent access
Push-In Plus: PTF-PU series-ideal for mass wiring, high vibration resistance
- النماذج المتوقفة
PTF08A-E / PTF14A-E are discontinued with limited stock.
Use PTFZ series as the preferred replacement.
> ملحوظة: PTF series sockets are rated 10A/250VAC, dielectric strength AC 2000V, operating temp −25 °C to +55 درجة مئوية, suitable for 0.5–2.5 mm² copper wires.
